  • page 791 ) performed calcite-graphite carbon isotope thermometry on 150 marble samples from the western Central Metasedimentary Belt (CMB) of the Ontario segment of the Grenville Province, which represents the deeply eroded and exposed core of a major mountain chain that existed one billion years ago.

  • The authors also found unusually high carbon isotope ratios ( 13 C/ 12 C) in the sample which provides a useful chemical marker to correlate rocks that formed in similar marine settings at around the same time roughly 1.3 billion years ago, well before the large mountain-building event.

  • stable-isotope
  • In this research area, UWAB faculty and students use paleontology and stable-isotope geochemistry of ancient (Archean eon) sedimentary rocks to determine when the main forms of microbial metabolism arose and whether this caused environmental change in the atmosphere and oceans. (washington.edu)

  • Studies conducted on mice revealed healthy eggs accumulate a large amount of zinc-50 per cent more than other important metals like iron-in healthy women to attain maturity and be ready for fertilisation. (org.in)
  • implications
  • Researchers at the University of Missouri have found that zinc plays a key role in promoting fertility in males, a discovery that has implications for improved in vitro fertilization and artificial insemination in livestock, and for human infertility diagnostics and therapies. (phys.org)
  • various
  • Scientists can use amounts of various isotopes as something like fingerprints at a crime scene. (sciencenewsforstudents.org)
  • Sutovsky and doctoral student Karl Kerns used a state-of-the-art image-based flow cytometer-which can take images of up to 2,000 cells per second and track biomarkers such as zinc with fluorescent dyes-to monitor zinc localization during various stages of capacitation in sperm cells. (phys.org)

  • I used to be a lot more into astronomy than I am now, and back in the 70s/80s, the thought that the moon was caused by a collision was not laughable, but looked at askance. (slashdot.org)
  • Scientists think that the moon was created in an ancient space collision. (sciencenewsforstudents.org)

  • This study gives us tools to approach the problem more efficiently by demonstrating the importance of zinc -both as a mediator of fertility and as an indicator we can use to identify issues with sperm. (phys.org)
